ABSTRACT:
A method for imprinting a pattern onto a blade of a fan includes the steps of 1) forming a blade with thermoplastic material by injection-molded; 2) coating an ink layer of wooden pattern onto the blade made from step 1) with a suitable printing device at room temperature; 3) drying the ink layer on the blades with infrared radiation during the transferring; 4) coating a protecting layer onto the ink layer with a suitable printing device at room temperature; 6) drying the clear UV layer at room temperature and then further drying the clear UV layer with ultraviolet radiation in a dryer such that the ink layer and said clear UV layer are polymerized with each other until the clear UV layer is completely cured and hardened.
